CiGAR-MAKiNG MACHINE.

Application filed. April 15, 1912.

To all whom 2'25 may concern:

Be it known that T, CHRISTIAN F. BREMER, a citizen of the United States,residmg at Tampa, in the county of Hillsboro, State.

of Florida, have invented certain new and useful Improvements inCigar-Making Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in cigar making machines.

The principal object of the invention is to provide a machine which isdesigned for the manufacture of better grade cigars where imitations ofhand-work is desired.

Another object of the invention is to provide a cigar making machine inwhich a novel means is employed for bunching the tobacco previous toapplying the wrapper.

A further object of the invention is to provide a machine for thepurpose described which can be operated by one bunch breaker on one sideand one cigar roller on the other side.

A still further object of the invention is to provide a machine of thecharacter described in which the rolls are automatically opened andclosed thereby avoiding the necessity of the operators manuallyperforming that work.

A still further object of the invention is to provide a machine of thecharacter de scribed which is simple in construction, it being composedof a minimum number of parts, is ositive in operation and is cheap tomanufacture.

With these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction with in the scope ofthe claims may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawings: Figure 1 is an enlarged longitudinal sectional viewthrough the bunching mechanism of a cigar making machine constructed inaccordance with my Specification of Letters Patent;

invention, Fig. 2V is a side elevational View of the complete machine,Fig. 3 is a vertical longitudinal sectional view through the machineshowing the bunching mechanism in elevation, Fig. 4: is a transversesectional view taken through the power shaft, Fig. 5 is a perspectiveview of a mold section, showing the tobacco receiving recess, and Fig. 6is a similar view of the mold section, but showing the opposite facethereof.

Like reference numerals designate corresponding parts in all the figuresof the drawings.

Referring to the drawings, A designates a bench which includes a top 5that is suit ably supported by legs 6 and braces 7. A transversepartition 8 centrally extends across the top 5, and side-boards 99 arealso secured to the top end of the partition.

Centrally formed in the top 5 is a longitudinally disposed rectangularopening 10, said opening extending on opposite sides of the partition 8,and located in this opening is my improved bunching mechanism which isdesignated as a whole by the reference letter B. Front and rear shafts11 and 12 respectively are disposed transversely across the opening 10on opposite sides of the partition 8, these shafts being rectangular incross section and having trunnions 11 and 12 respectively extending fromthe ends thereof and suitably journaled in bearings 13 mounted on thetop 5 on opposite sides of the opening 10. This mechanism includes anendless conveyer, which is designated as a whole by the referencenumeral 1 1. This conveyer is formed from a series of abutting moldsections 15, each section being rectangular in shape and having a crosssectional area equal to that of either of the shafts 11 or 12. Formed inone of the abutting faces of each section 15 is a longitudinallydisposed recess 16 which corresponds in size to the shape of the cigarto be formed. This recess opens at its ends, as indicated by thereference numerals 16 and 16*, the former opening being larger than thelatter. Projecting from the opposing face of the next adjacent section16 is a complementary projection 17 which is adapted when the sectionsare disposed in abutting relation to partially extend into the recess16, and thereby compresses the tobacco. These sections are fixedlyconnected to an endless belt 18 which is trained over the shaft 11. Alsoformed in one face of each section 15 and between the recess 16 and theinner edge of said section is a longitudinal groove 19 which receives arib 20 which projects from the inner edge of the opposing face of thenext adjacent section, said projection 20 being disposed below theprojection 17.

Fixed upon each trunnion 11 of the front shaft 11 is a ratchet 21 andalso fulcrumed upon each trunnion 11 is a lever 22 which carries aspring pawl 23 for engagement with a respective ratchet. Each lever 22is slightly bent forwardly, and connected to the upper forward endthereof is one end of a connecting cord 24, said cord being connected attheir lower ends by a treadle 25 which is hingedly connected to atransverse frame member 26. A spring 27 is connected at one end to thetreadle 25 and at its other end to the top 5 of the bench and serves tonormally hold the treadle 25 in its upright or normal position. It willbe seen that the shafts are rotated through ninety degrees at eachdownward movement of the treadle. In order to prevent the sections frombuckling when in travel, there is provided on either side of theconveyer 14 a pair of brackets 2828, and these brackets support a transerse roller 29 which is disposed above and engageable with the sections15 as they pass thereunder.

In operation, the operator at the front end of the machine places asufficient amount of tobacco in the section 15 which is arranged at thefront of the mechanism above described. The treadle 25 is then depressedagainst the tension of the spring 27, and as a result, the levers 22 arerocked upon their fulcrum and through the medium of the pawls 23engaging with the ratchets 21, the power shaft 11 and consequently thedriven shaft 12 is rotated for one step, this movement swinging thesection 15, in which has been previously placed the tobacco, upwardlyupon the shaft 11, and at the same time brings the next section 15 intoproper working position. As the sections are thus caused tointermittently travel rearwardly, the tobacco is compressed within therecesses 16 by means of the projections 17. As the section containingthe compressed tobacco reaches the rear end of the mechanism, thesections 15 will automatically swing around the shaft 12 as will bereadily understood, and when a section 15 is disposed against the rearface of the shaft 12, the recess 16 of the section 15 on said shaft 12is thereby automatically opened. By this means it will be observed thatthe mold is automatically opened so as to permit the operator to readilyremove the compressed tobacco. Simultaneously with this movement thesections at the front end of the machine are automatically swung intoposition for receiving the tobacco within the recesses 16*.

lVhat is claimed is:

1. In a cigar making machine, the combination of a pair of spacedrectangular shafts, a conveyer trained around said shafts including aseries of transversely arranged abutting mold sections, and a guideroller disposed transversely above the conveyer for engagement by thesections said roller being wholly above the plane of movement of thesections.

2.
